You can apply a patch by using the MapR Installer, by using the command line (a manual process), or by using a MapR Installer
Stanza.

Deleting an AWS Stack

MapR resources in AWS are grouped together, making it easy for you to remove them.
You can use the MapR Installer Destroy button to delete an
AWS stack in one operation. The Destroy button appears when
the MapR Installer detects cloud installations that were created using MapR scripts.

You can also use AWS menu commands to delete an AWS stack. Because the MapR stack is
an Auto Scaling Group, deleting it using AWS menu commands requires some extra
steps. First, you must disable certain AWS processes that protect against shutting
down the stack. Then you must delete the stack.

Delete an AWS Stack Using the Destroy Button

To remove an AWS stack using the MapR Installer, you
can use the Destroy button:

Log in to the MapR Installer.

On the status page, click the Destroy button. A
confirmation box asks if you want to delete the MapR cluster.

We will start to delete your cluster and all the resources associated with it. Please check the AWS console to verify that all resources were deleted successfully.

You can monitor the status of stack deletion in the AWS console.

Delete Suspended Processes

Use these steps if you want to delete your MapR stack
using AWS menu commands. You do not need to use these steps if you use the MapR
Installer Destroy button. To remove a MapR stack using AWS
menu commands, you must delete suspended processes and then delete the
stack.

Click Services > EC2.

In the left navigation pane, under Auto Scaling,
click the link to Auto Scaling Groups.

In the list of Auto Scaling Groups, find and select the name of your
stack.

Tip: Type the first few letters of the stack name in the
Filter field to find the stack.

Click the Details tab to select it.

Click Edit.

Scroll down to the Suspended Processes
section:

Click the "x" in each of the suspended processes to delete it.

Click Save.

Delete the Stack

You do not need to use these steps if you use the MapR
Installer Destroy button. To remove an AWS stack manually,
you must delete suspended processes and then delete the stack.
